Selena Gomez was "very happy" to see her ex-boyfriend Justin Bieber win his first ever Grammy award.
The 23-year-old singer - who had a four year on/off relationship with the hunk - admitted she was pleased to see her former flame win the Best Dance Recording prize for his hit song 'Where Are Ü Now'.
She said: "I'm very happy for him. Honestly, so cool."
Selena also praised Skrillex and Diplo, who collaborated with the 21-year-old star on his winning song.
She added: "They have such a cool energy amongst all of them to be able to create something like that. It's really great."
The raven-haired stunner was in a celebratory mood at last night's (15.02.16) ceremony, which took place at Los Angeles' Staples Center, as she attended the awards with her best friend Taylor Swift, who won Best Music Video for 'Bad Blood'.
Speaking about the win, Selena - who starred in the video herself - told 'Entertainment Tonight': "Oh, I was so happy!"
Taylor and Selena looked incredible as they walked the red carpet together, and the 'Hands to Myself' hitmaker admitted she chose her dazzling Calvin Klein cut-out gown because she wanted to feel like a "sparkly ball" for the evening.
She explained: "I am wearing Calvin Klein and I am very happy because I wanted to feel like a blue, sapphire sparkly ball. I just love it."
